Evaporator Temperature Sensor / Switch: Testing and Inspection
Test
Compare the resistance reading between the No. 1 and No. 2 terminals of the evaporator temperature sensor with the specifications shown in following
graph; resistance should be within specifications.
1. Dip the sensor in ice water, and measure resistance.
2. Pour hot water on the sensor, and check for change in resistance.
CAUTION: The sensor uses a thermistor which can be damaged if high current is applied during testing. Therefore, use a circuit tester with an output
of 1 mA or less at the 20 K Ohms range.
